Application filed June 16,

To all whom it may concern:

Be it known that I, WILLIAM MICE-ism, a citizen of the United States, residing at Atlantic City, in the county of Atlantic and State of New Jersey, have invented certain new and useful Improvements in Roofing Fabrics, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to new and useful improvements in roofing fabric and has for its principal object the provision of such fabric having inturned longitudinal edges "so that when the roofing is laid in strips the inturned edges of adjacent strips may be interlocked, the edges being inturned prior to winding the fabric in'rolls.

A further object resides in cutting the ends of the strips of fabric in such a manner that they may be turned back to form tongues, between the inturned longitudinal edges, the tongues of the meeting ends of strips adapted to be interlocked for connecting the strips.

With the above and other objects in view, which will appear as the description proceeds, my invention consists of the novel details of construction and arrangement of parts, described in the following specification and illustrated in the accompanying drawings, and while I have illustrated and described the preferred embodiments of the invention, it will be understood that such changes may be made as will fall within the scope of the appended claims. 4

In the drawings:

Figure 1 is a perspective of a roll of roofing fabric.

ig. 2 is a fragmental top plan. Fig. 3 is a longitudinal vertical section on the line 33 of 1d igure 2.

. Fig. A: is a transverse vertical section on the line H of Figure 2.

Fig. 5 is a fragmental transverse section showing the manner of interlocking the adjacent strips of fabric, and

Fig. 6 is a transverse vertical section on the line 66 of Figure 2.

In the drawings, 1 indicates a strip of fabric of any desired construction adapted to be rolled, said fabric being coated with tar and covered, with the exception of a narrow strip along each longitudinal edge with tudinal flanges 2 of adjacent strips interlocking, nails 5 being driven through the flanges in the manner shown. It will be understood that both sides of the fabric are coated with the tar and gravel with the ex ception of the inturned flanges so that either surface thereof may be exposed to the weather. When the strips are applied the nails are all covered as shown so that there willbe no chance of leaking at these points. When it is desired to connect the ends of the strips, the tongues l are bent back and interlocked and a nail may be driven therethrough. As previously stated, the longitudinal edges will be turned inwardly before the fabric is rolled and by doing this the fabric may be easily applied to the roof and v the edges of adjacent strips interlocked. If

desired any ornamental design may be formed on the surface of. the strips.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is: 1

l. A roofing fabric covered with an asphalt composition on both faces with the exception of a relatively narrow strip along-the longitudinal and transverse edges, all of said un covered edges adapted to be folded over the body of the fabric to form members adapted to be interlocked with adjacent strips of the fabric, the parallel faces of the inturned portions being disconnected from the cov-- ered portions of the fabric.

2. An article of manufacture comprising.

a roll of roofin fabric covered with an asphalt compositmn on both faces with the exception of a relatively narrow strip along the lon itudinal and transverse edges, both longitu inal uncovered edges being folded,

prior to rolling, over the body of the fabric to form members adapted to be interlocked with adjacent strips of the fabric, the parallel face of the inturned portions being disconnected from the covered portion of the fabric.

3. A roofing fabric having both of its longitudinal edges folded inwardly over the body of the fabric, the parallel faces'of the 1 ,eaaaoo
